Here is me remembering Jiaqi Ge, a former colleague and acquaintance at the University of Leeds, and some of her work that I find interesting. She tragically passed away last year. theworldinmodels.substack.com/p/jiaqi-ge-t...

Back from holiday with a bang 💫 Am pleased my article Artificial Utopia is now published in the journal Futures. lnkd.in/e_fnEbg3 This article conceptualises thinking about Utopian and radically socially innovative societies with the help of computational simulations.

Interestingly enough there is even a paper on this that finds AI biases the review process towards more positive outcomes. arxiv.org/abs/2405.02150 Perhaps. But I think the final outcome is yet to see and regardless of the sign of the outcome, the quality possibly decreases.

I think using AI to refine reviews as any other text is fine, as long as it remains a high quality honest review, but in my case it went so far that the "reviews" clearly just rephrased limitations from my own text and any AI detector would immediately detect it. I felt cheated.

And lastly I speculate about the future and general ability of computational research to aid in such democratisation and scientific efforts. What are its limits? Ethical propblems?

Specifically, I map exisiting simulation methods to existing challenges in niche democratisation efforts such as citizen assemblies and democratic firms to generate a better understanding of how computational simulation may aid social, political and economic innovation. Hope you enjoy!✍️

Crazy that in this whole tumult around Zelensky and Trump, the Americans, Trump and his friends, also just swept under the rug that Russia already allied with North Korea and North Korea literally has troops fighting alongside Russia against Ukrainians. But sure *Zelensky* gambles with WW3.

Citizen assemblies (CA) are often thought to decrease polarization on sensitive issues. However there is a surprising amount of literature showing other effects. E.g. this experimental study found students became *more* ideological through a modelled CA. www.tandfonline.com/doi/full/10....

Not sure I agree with everything and the generic distinction between maps and equations and how it relates to the discussion. (An equation can certainly be used to express a map e.g. y = ax + b). But this is nevertheless the only piece that in my view made a proper conceptual advance on that front.

I honestly kinda wish I had written it 🙃, I thought sooo much about equilibrium myself in my free time and always found the standard critique of "economics is too mechanical and unsystemic" a bit underwhelming. But this one is quite good.
